XML模式声明

Question

我有一个像下面这样的xml输入，并希望为它创建一个XML模式。但是我创建的模式似乎有问题。是否可以向我展示如何为下面的xml创建模式。

-ownerName在农场元素

<Country> 
    <state> 
    <farm farmOwnerName="Jerry" produce="apple"> 
     <established>1974</established> 
     <totalWorker>30</totalWorker> 
    </farm> 
    <farm farmOwnerName="Ronald" produce="apple" quality="best"> 
     <established>1969</established> 
     <totalWorker>15</totalWorker> 
    </farm> 
    <farm farmOwnerName="Richard" produce="lemon"> 
     <established>1970</established> 
     <totalWorker>20</totalWorker> 
    </farm> 
    </state> 
    <ownerDetail age="70" ownerName="Ronald"> 
    <bornIn>Australia</bornIn> 
    </ownerDetail> 
    <ownerDetail age="50" ownerName="Richard"> 
    <bornIn>Canada</bornIn> 
    </ownerDetail> 
</Country> 

架构我，我编码为farmOwnerName ownerDetail元素引用低于：

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" > 
<xs:element name="state" type="xs:string"/> 
<xs:element name="established" type="xs:integer"/> 
<xs:element name="totalWorker" type="xs:integer"/> 
<xs:element name="bornIn" type="xs:string"/> 

<xs:element name="Country"> 

<xs:complexType name="farm"> 
    <xs:sequence maxOccurs="unbounded"> 
     <xs:element ref="established"/> 
     <xs:element ref="totalWorker"/> 
    </xs:sequence> 
    <xs:attribute name="farmOwnerName" use="required"/> 
    <xs:attribute name="produce" use="required"/> 
    <xs:attribute name="quality" use="optional"> 
     <xs:simpleType> 
      <xs:restriction base="xs:token"> 
       <xs:enumeration value="best"/> 
       <xs:enumeration value="normal"/> 
       <xs:enumeration value="low"/> 
      </xs:restriction> 
     </xs:simpleType> 
    </xs:attribute> 
</xs:complexType> 

<xs:complexType name="ownerDetail"> 
    <xs:sequence maxOccurs="unbounded"> 
     <xs:element ref="bornIn"/> 
    </xs:sequence> 
    <xs:attribute name="age" use="required"/> 
     <xs:attribute name="ownerName" use="required"/> 
</xs:complexType>

您XML Schema为给xml应该如下

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" > 
    <xs:element name="Country"> 
    <xs:complexType> 
     <xs:sequence> 
     <xs:element name="state"> 
      <xs:complexType> 
      <xs:sequence> 
       <xs:element name="farm" maxOccurs="unbounded" minOccurs="0"> 
       <xs:complexType> 
        <xs:sequence> 
        <xs:element type="xs:short" name="established"/> 
        <xs:element type="xs:byte" name="totalWorker"/> 
        </xs:sequence> 
        <xs:attribute type="xs:string" name="farmOwnerName" use="optional"/> 
        <xs:attribute type="xs:string" name="produce" use="optional"/> 
        <xs:attribute type="xs:string" name="quality" use="optional"/> 
       </xs:complexType> 
       </xs:element> 
      </xs:sequence> 
      </xs:complexType> 
     </xs:element> 
     <xs:element name="ownerDetail" maxOccurs="unbounded" minOccurs="0"> 
      <xs:complexType> 
      <xs:sequence> 
       <xs:element type="xs:string" name="bornIn"/> 
      </xs:sequence> 
      <xs:attribute type="xs:byte" name="age" use="optional"/> 
      <xs:attribute type="xs:string" name="ownerName" use="optional"/> 
      </xs:complexType> 
     </xs:element> 
     </xs:sequence> 
    </xs:complexType> 
    </xs:element> 
</xs:schema>
